For venturi injectors to work, they need the right pressure and water flow. I suspect that this is not going to work for you. I am running into a similar problem with this type of injectors (not this one in particular). The 4th photo of this item shows the performance of this injector (1/4 inch A12057). Indicated water flow is between 50L (0.05m3) and 200L (0.2m3). The flow you are using is at the borderline of this injector not working (assuming that the flow to the garden is exactly 50L and not slightly below). Also check the pressure. Again, as indicated for this injector in the photo description, it requires between 28 and 43 psi for input and a maximum of 14 psi at the outlet (drip line). If you have higher than 14 psi at the drip line the injector will not work either, because venturi injectors require a certain pressure drop between inlet and outlet for them to perform. If there is anyway you could add some drippers to increase flow this might work. That's the curse of the small garden, videos you see online do not mention all these details. As I said before, I do not have experience with this injector in particular, but I will go ahead and buy it because based on my calculations I have a flow of about 50 gallons/h (~200 L/h), so this should work. Good luck!
